Why Safe Links Rewrites URLs and What Senders Can Do

What is Safe Links?

Safe Links is a Microsoft Defender feature that rewrites links in emails (e.g., na.01.safelinks.protection.outlook.com).

It scans every link for phishing or malware before you open it.

This happens automatically for all users.

Can a sender stop Safe Links from rewriting their URLs?

No.

Safe Links applies to every link, even from trusted senders.

There is no way for a sender to bypass it.

So what can a sender do?

They can’t disable Safe Links, but they can make their website and emails look safer and more trustworthy to Microsoft’s security systems.

Here are the steps that actually help:

1. Use proper HTTPS

The website must have a valid SSL certificate.

Unsafe or outdated certificates reduce trust.

2. Avoid URL shorteners

Links like bit.ly or tinyurl are often flagged as suspicious.

Use full, clean URLs instead.

3. Maintain a good domain reputation

Microsoft tracks domain reputation.

A sender improves reputation by:

• Hosting on a reputable provider
• Avoiding spam‑like content
• Keeping the site malware‑free
• Using a domain that isn’t brand new

4. Set up SPF, DKIM, and DMARC

These email authentication records prove the sender is legitimate.

Without them, emails look more suspicious.

5. Avoid hiding links inside images or buttons

Security systems prefer visible, plain URLs.

Hidden links look like phishing.

6. Use a consistent sending domain

Switching between Gmail, a custom domain, and marketing platforms lowers trust.

Consistency helps reputation.

7. (Business only) Submit URLs to Microsoft

If the sender believes their site is being incorrectly flagged, they can submit the URL for review through the Microsoft 365 Defender portal.

This can improve reputation over time.

What the sender cannot do

• They cannot stop Safe Links from rewriting URLs
• They cannot be allow‑listed by email address
• They cannot force Outlook to trust their domain
• They cannot disable Safe Links for specific recipients

Safe Links treats all links equally for safety.
